HORIZONTAL-CURVE CONSTRUCTION FOR CABLE RAILWAYS.,

SPECIFICATION forming part of Letters Patent; No. 371,601, dated October 18, 1887, Application filed February s, 1887. Serial No. 227,439. (No model.)

To all whom it may concern:

Be it known that I, HENRYM. LANE, a citizen of the United States, residing at Cincinnati, Ohio, have invented new'and useful Improvements in Horizontal-Curve Constructions for Cable Railways, of which the following is a specification.

My invention relates to horizontal-curve constructions for cable railways. Its object is to produce an efficient and economical construction and arrangement of the system of horizontal pulleys and their immediate supports and connecting parts, and to facilitate the removal, replacement, and repairs of the port.

same.

It also consists in the construction and arrangement of the slot-rails and tunnel-yokes,

with reference to the lateral support of the grip in passing curves, and in certain other minor features, hereinafter more fully set forth. Mechanism embodying my inventionis illustrated in the accompanying drawings, in which- Figure 1 is a cross-section of the road-bed through the track-rails, slot-rails, and a curvepulley, showing one of the tunnel-yokes (as constructed for curves) in elevation Fig. 2, a detail section in the planemc of Fig. 1, indicating the general web structure of the yoke-exftensionand of the covering-plates resting thereon; Fig. 3, a general plan view of the road-bed, including two consecutive yokes,

and showing one of the curve-pulleys in position; and Fig. 4. and 5, details of the socketrest for the hinged pulley-bearing arm.

Referring now to the drawings, A designates one of the cast-iron yokes used upon curves. The left-hand half of said yoke, as indicated in Fig. 1, with its slot-rail at, its brace 72, and tiebar 0, (forming a bracket supporting the lefthand track-rail R,) is identical in construction with that of the yoke described by me in former patents, and need not be further- For use upon curves, however, the yoke is cast with a projection or web, A, extending at one side to the vertical line of the track-rail R, for which rail it forms a sup- This extension is preferably cast in the form of a partial or entire web similar to that of the body of the yoke, and strengthened by a marginal flange, d, similar to that of the yoke itself, of which it is an extension.

The extension A is carried under the trackrail R to-form a bottom support, and is formed to fit the contour of the rail at the inside of the latter, the web at being enlarged at the side of the rail to admit a bolt horizontally through itself and the rail, securing the latter in position and preserving the proper gage of the track.

When the yoke is in position it occupies, with its lateral extension, a radial relation to the general curve of the track, the said extension being toward the center of said curve. The slot-rail a is in this instance arranged with its main webin a vertical plane, the corresponding jaw of the yoke being formed to secure it in such position upon a bracket or ofiset, a from the inner face of the yoke, constituting a bottom support. yoke by bolts passing through the-flanges ofthe yoke from the outside and screwed into tapped holes in the slot-rail to present a flush surface with said rail within the tunnel, so that in case the bolts work loose they recede from such flush surface. As thus constructed and arranged,the said slot-rail a forms a bearingrail, against which the grip G slides,and which takes the lateral strain of the cable 0 in pass- This slot-rail is secured to the 7 0 ing around curves, as indicated by the posi- 8c tion of the grip device G in Fig. 1, and the fastening-bolts can under no circumstances form an obstruction. A ledge, a is formed upon the outside of the slot-rail a, constituting a bearing for the covers 0, which abut against 8 5 each'other in radial lines of the curve, meeting upon the flanged upper edge, (I, of the extension A, as indicated in Fig. 2, and held laterally by their strengthening-webs w,fitti ng within and between contiguous partitions A.

The yokes and extensions rest upon a concrete foundation, as indicated by the broken lines in Fig. 1, the surface of that portion of said foundation beneath the extension inclining inward to drain into the bottom of the 5 IOO into the main tunnel, and divided radially by the extension A, constituting partition-walls.

In this side tunnel, between each two yok'es and partitions, I mount a horizontal curve pulley, D, in the following manner: The pulley D is suspended by a stud, s, from a supportingarm, E, hung pivotally in hangers F, bolted to the outside of the slot-rail a in the manner already described for securing the said slotrailto the yokcs. The outer end of the arm E has its bearing in a suitably-formed socket against the inside of the rail R, the horizontal flange of the rail being rccesse'd, as indicated in Fig. 3, to permit the arm to be forced downward a little to one side of its true vertical plane ant spring under said flange sidewise. To secure the arm againstlost mo tion and displacement, a short arm,f, with a camshaped end, is pivoted to the side of the main arm E, near its outer end, which, when said main arm is in position, is turned so as to elongate the arm and lock it in position by lineal compression between its end supports. To insure a secure holding of the arm E, I cast or attach to the side of the rail R a socketpiece, 9, formed as shown in Figs. 4 and 5, which has an opening corresponding with the recess of the horizontal'fiange of the rail R, and is offset sidewise below to admit the arm E first downward and then sidewise into a holding-socket, securing it against vertical displacement, where it is locked by the camarm f, acting against the surface 9 of the socket-piece.

The hangers F are formed as two depending arms orhooks cast with and upon a base-plate, f, which rests against and is bolted to the outside of the slot-rail a, as indicated in Fig. 3. The arm extends between the hangers F, and is upheld upon lateral pivots 1), extending at each side of the arm and resting in the hangers. The partsare to be so proportioned and adjusted as to allow the arm E to be readily loosened by turning the loeking-camf, which may then be turned up and used as a handle to swing the arm E upon its pivotal bearing and elevate the pulley D out of its cavity into a vertical position. The entire pulley device may be then lifted bodily out of the hangers and cavity, if desired.

I11 the center of the arm E is an enlargement, through which the stud 8 passes and is secured. I form in this enlargement, adjacent to the central stud perforation, an oil-chamber, h, open above and there provided with a hinged lid, and through the bottom of said chamber drill an oil-channel to the wheel-bearing below. The chamber is made large enough to contain sufiicient oil to last between inspections made at proper intervals.

I claim as myinvention and desire to secure by Letters Patent of the United States- 1.
